Cinaid knows that the taste of little folk flesh will further madden your sapling. He orders you to make your way to Hoarhallow to collect toes to feed your sapling.
'Let us talk of the Little Folk of Hoarhallow a moment. Have you tasted their flesh? I have. It is succulent. When we gather their toes and grind them into pulp we will mix the flesh into the soil of your sapling and like all the other Free Folk, the sapling will know their taste. It will learn that their flesh is its sustenance and it will hunt them with impunity. Think of that, ${PLAYER}.'
Make your way south to Hoarhallow and gather toes from the Little Folk there that you may feed the succulent flesh to your sapling.
